Rack Mounting the Switch

The following topics are covered in this section:
The switches can be installed in two-post Two-post Rack Mount or four-post Four-post Rack Mount (Optional) racks. The appropriate accessory kit provides components for installing the switch in the rack. The chassis can be mounted in the following three positions:
  • Front
  • Center
  • Back (rear)

Attaching Mounting Brackets to the CCS-755 Two-post and Attaching Mounting Brackets to the CCS-758 for Two-post show examples for attaching mounting ears to the CCS-755 and CCS-758 chassis to support each of the three mounting locations.

Note: Four-post rack mount kit is optional.

 

Illustrations in this chapter depict the mounting of a chassis in a single orientation. After completing the instructions for your rack type, proceed to Cabling the Modular Switch.

Two-post Rack Mount

The switch can be mounted in either forward orientation (line cards and supervisors facing forward) or backward orientation (fans and PSUs facing forward). For each of these orientations, the switch supports a front, center or rear mount into a two-post rack.

The accessory kit includes the following two-post mounting parts:
  • Two-post rack cradle
  • mounting brackets
  • 18 screws
    Note: The following illustrations highlight a front-mount.

    After completing the two-post Installation, proceed to Cabling the Modular Switch.

Four-post Rack Mount (Optional)

The switch can be mounted in either forward orientation (line cards and supervisors facing forward) or backward orientation (fans and PSUs facing forward) in a four-post rack.

The accessory kit includes the following four-post mounting parts:
  • 4-post rack cradle
  • mounting brackets
  • 18 screws

Rack Mounting the CCS-755 for Four-post

To mount the switch to the rack, perform the following tasks.

Attaching Mounting Brackets to the CCS-755 for Four-post

Attach the mounting brackets to both sides of the chassis using the screws provided in the kit for the desired orientation and position. The following figure shows the CCS-755 chassis with the mounting brackets for Forward-Front, Forward-Center, and Backward-Front mounting.

Note: Note Center and rear mount are not supported for four-post rack mounting.

 

Inserting and Securing the Cradle to the Racks for Four Post 755

  1. Insert two screws loosely in the two front rack posts and two in the back two rack posts at the same level for the figure below.
    Figure 10. Attaching Mounting Screws to the Rack Posts for 755

  2. Buckle the straps on the cradle together, prior to installation, so the left and right sides are angled slightly inwards for the figure below.
    Figure 11. Buckling the Straps

  3. Pull out the rear sliding rails slightly beyond the back rack posts.
  4. Insert the cradle so that the notches in the cradle engage behind the loosely mounted front screws for the figure below.
  5. Slide the rear sliding rails back in so that they are flush with the back rack posts, the notches in the cradle engage behind the loosely mounted screws, and the bottom of the cradle is horizontal and level for the figure below.
